How to decrease the width of the tv screen

you need install graphics driver than fix the problem

the source is ok; 13volts... but no pwer -on

My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display problem (purchased Aug. 2008, manufactured July 2008). Vertical multicolored lines appeared on the screen just left of center. The band of thin vertical bars is 5.5 inches wide. The lines are about 1/16-inch wide. They are stationary, always exactly in same place. They over-ride any other picture on the screen (no transparency). They are there all time even with no video inputs to the TV after the unit is turned on. See picture #1. The TV works well in every other respect, but, obviously, it is annoying to watch the picture with the color band blocking about 1/6 of the picture.

I already swapped out the TCON board with no improvement and replugged the TCON board cables with no improvement.

Most likely it is the flat panel tab bond failure (panel made by Samsung). Further solution updates will be on my Facebook page.

This is the TV. Look for an aspect ratio or picture size or other wording button on the TV's remote control and READ your TV owner's manual. John

you need to find the picture format setting on the tv and set this to AUTO so that when the transmitted picture is 4:3 or standard it will show the 2 black/blue blocks down each side of the screen.
depending on IF your tv has this option. normally pressing menu will give you a picture option or some times there is a single button press on the remote.for example the sony tv is normally the blue "teletext" button.

Both the TV and the Cable box have Aspect(height/width) settings. You must confirme the setting on the cable box and then do the TV.

1. Set TV to Native, this should show image exactly as the cable box sends it.
2. change Aspect settings on the cable box until you get one that works
3. if you get a good one, then your OK. You will just need to find a setting between the 2 devices that work for you. Also, these settings may change automatically for the TV or cable box based on the channel

look for horizontal control

This trouble symptom picture wide or"blooming", the picture becomes dim even with the brightness control full on,and there is an abnormal enlargement of picture or raster.Usually,the enlargement is uniform,but there may be some defocusing.In some circuits,the brightness control operatesin reverse(rotating the control for an increase in brightness produces a decrease) after reaching a critical point on the control. If the picture wide is not accompanied by insufficient width(a symptom of horizontal output failure) the probable cause is a high volatge circuit ony,particularly the HV rectifier and HV winding.Any circuit problem that reduces but does not completely eliminate the high-voltage output to the picture tube second anode can cause overscan. The most likely defects are leaking high-voltage capacitors,defective high voltge tube rectifiers,leaking high voltage leads,defects in high voltage circuit protective resistance,and shorted turns in high voltage winding of the flyback transformer.

Hope this may help you;

if you have a wide flatscreen tv it could be that the picture size is in the wrong mode. under the mode button on your tv remote should be two buttons labeled wide and zoom. try pushing these buttons to adjust the tv screen size.

In menu, there is a selection for wide screen 16X9 or 4.3 to 1
normal width......check owner manual...................T.
